“You offered a first purchase discount and then told me it didn't apply to the bike helmet I ordered? That seemed like a bait and switch. I still ordered the helmet but felt deceived by your offer. Not a good first impression!”
Response from campman.com:

Thank you for your feedback. Our system is set up to default to the lowest available price, and the helmet you ordered was already on sale for over 50% off. This means the sale price was lower than the coupon price and you received the best available deal.

Additionally, the coupon signup clearly states that it only applies to full priced items and cannot be combined with other offers. Here's a screenshot: https://app.screencast.com/fvJS1t5PEPi1a

We love giving hookups on quality gear, but we still need to keep the lights on around here. Your coupon will remain active in our system and attached to your email for whenever you choose to use it.

Cheers,

Campman Support
